Hannah DeVyldere and Matthew Bowden did great on their final REU presentations on Monday. Hannah discussed her work on manipulating nanoparticles inside an electron microscope, and Matthew discussed his work on optimizing electron holograms for sculpting electron beams. It was obvious they enjoyed their projects and made a lot of progress, and they both had some good questions at the end. Good job!
Fehmi Yasin was lead author and presenter on the poster “Development of STEM-Holography” for the Microscopy & Microanalysis (M&M) conference in Colombus, Ohio last week. M&M is one of the premier international conferences for discussing all types of microscopy-related research, and draws researchers and engineers from many different areas of science and industry. It also draws scientists like us interested in electron physics.
In this work, Fehmi and the other authors (Tyler Harvey, Jordan Chess, Jordan Pierce, and myself) discuss our use of a single nanofabricated diffraction grating to divide a beam of electrons inside an electron microscope, such that each electron in the beam moves along two separate paths at the same time (one of those interesting effects allowed by quantum physics). Fehmi and the other authors are developing ways to use this technique to image difficult-to-see structures at the nanoscale inside a transmission electron microscope (TEM).
In addition to getting a Student Meeting travel award to attend this meeting, upon presenting the poster Fehmi also won First Place poster prize for “Advances in Instrumentation”! Thank you to the Microscopy Society of America (MSA) for sponsoring both of these awards. Thank you also to Tyler, Jordan C, and Jordan P for all your help to Fehmi on this exciting project, and for all of your contributions and great feedback on the poster!
